Communications Support Forums

Greeting all,

I recently purchased an XPR 6580 to convert to ham usage (analog and DMR). It is a H55UCH9LB1AN with a Tanapa number PMUF1410AD. It is a Connect Plus radio (sticker under the battery) that was converted to 3600 trunking. It is presently at FW R011024.

I have found the threads that explain in great detail how to convert from 3600 trunking to DMR, etc, but those files require a start of FW R011023 or earlier - this radio is already beyond that. I am using CPS 11.5 and it won't let me "upgrade" to an older FW, or "convert" to the DMR FW.

I think I need to downgrade the FW. Is that something I can do - or do I have to send it somewhere?

Thanks in advance for the help.

Bill
